MARKING-PEN.

To all whom it may concern Be it known that 1, JOHN J. MAGNUS, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Marking- Pens, of which I do declare the following to be a full, clear, and exact description, reference being had to the accompanying drawing, forming part of this specification.

The present invention has for its object to provide an improved construction of pen which, while susceptible of more extended use, is especially designed as a pen for marking letters, figures or like characters in bold outline.

The invention consists in the features of novelty hereinafter described, illustrated in the accompanying drawing and particularly pointed out in the claims at the end of this specification.

Figure 1 is a plan view of a pen embodying my invention. Fig. 2 is a view in side elevation. Fig. 3 is a view of the holder, this view being partly in elevation and partly in longitudinal section, the pen being removed. Fig. 4 is a detail plan View of the pen. Fig. 5 is a view of the pen in longitudinal section on the line 5-5 of Fig. 4.

The body 10 of the pen-holder may be of any suitable material, and as shown, is provided with a threaded socket 11 adapted to receive the correspondingly threaded shank 12 of the pen stock or carrier 13. Preferably, the pen stock or carrier 13 is bifurcated, forming arms 14 and 15 between which the pen will be secured. The arm 14 of the pen stock or carrier is provided upon its inner surface with a stud or pin 16 and adjacent its outer end is formed with a transverse groove or notch 17, and from the arm 14 projects the screw threaded stem 18 that passes freely through a hole formed in the arm 15 and carries a threaded thumb nut 19 that bears upon the outer surface of the arm 15. The arm 15 is preferably made somewhat thin, as at 20, so as to give resiliency to the arm 15, the spring of the part 20 tending to move the arm in outward direction. The inner face of the arm 15 is formed with a notch 21 corresponding and opposite to the notch 17 at the end of the arm 14.

My improved pen is preferably formed of Specification of Letters Patent. n Patntgd NOV. 24 1914 Application filed February 21, 1913.

resilient sheet metal bent to the shape shown 1n detail 1n Figs. 4 and 5 of the drawing.

The pen comprises upper and lower members 23 and 24 connected together at their inner ends and the member 23 is formed with'upturned side walls 25 between which the member 24'of the pen will fit. The free ends of the members 23 and 24 are beveled, I

as at 26, and the upper member 24 of the pen is formed with a longitudinal slot 27. Both the upper and lower members 23 and 24 of the pen are curved downwardly, as

clearly shown in Figs. 2, 4 and 5 of the drawing, and the tip of the upper member,

into which will project the stud 16 and the screw threaded stem or pin 18 when the pen is in position for use and the upper and lower members 23 and 24 of the pen are formed with transverse ribs 29 adapted to enter the transverse seats 17 and 21 of the arms 14 and 15, respectively.

When the pen is to be inserted in the holder, the thumb screw 19 will be turned outwardly, so as to permit the arms 14 and 15 to separate a sufficient distance to enable the pen to be slipped into position, as shown in Fig. 2, after which the thumb screw 19 will be tightened so as to insure the secure retention of the pen within the arms 14 and 15 of the holder. When thus in position, the pen is in readiness for use. When the pen is dipped into the ink or marking fluid, the side walls 25 will serve to retain a body of ink within the pen, thus enabling a considerable amount of marking to be done without replenishing the supply of ink. By adjusting the thumb screw 19, the outer ends of the members of the pen can be moved together and apart to regulate the flow of ink. It will be understood, of course, that a variety of pens having points of different dimensions can be used with the same holder and by loosening the thumb screw 19, the pens can be readily inserted into or withdrawn from the holder.

It will be understood that the precise details of construction above set out may be varied without departing from the spirit of the invention and that features of the invention may be employed without its adoption as an entirety.

I claim as my invention 1- 1. A pen of the character described having upper and lower members formed of resilient material, united at their inner ends and said upper member having a point at its free outer end and extending beyond the outer edge of said lower member for engaging the object to be marked.

2. A pen of the character described hav ing upper and lower members united at their inner ends and said upper member having a point at its outer end extending beyond the outer end of said lower member for engaging the object to be marked, said point being bent downwardly and extending beyond the end of said lower member.

3. A pen of the character described having upper and lower members united at their inner ends, one of said members extending beyond the other to engage the ob ject to be marked, in combination with a holder having arms for engaging the pen and a screw for adjusting the pen.

a. A pen of the character described having upper and lower members united at their inner ends, the inner ends of said members being formed with an open ended slot, in combination with a holder having arms between which said pen is held, a screw carried by said holder and passing through said pen and means at the ends of said arms for retaining the pen against longitudinal withdrawal from the holder.

5. A pen of the character described comprising upper and lower members united at their inner ends and said upper member having a point at its free outer end, said inner ends being slotted and said members being provided with offsets or projections, in combination with a holder having arms between which said pen is carried, a screw and stud adapted to enter the slotted inner portion of the pen, the outer portion of said arms being provided with. seats to receive the olisets or projections of the pen.
